Worked on it till 2 am this morning. Its cold here now so I took allot of breaks. To my suprise one of the lifters had collasped which was the ticking I have been hearing. No bent pushrods this time around though. Iwent ahead and replaced the cam and lifters anyhow with the factory cam since it was special order for me and I had it. I also advanced the cam 4degrees. Still missing though- a dead miss just like you pulled a spark plug wire. Plugs, wires and distributor have all been replaced in last six mo though. So I ran another compression test- 158-162 on all cyl with plugs removed and 20 sec cranking. (thought maybe blown gasket between cylinders). rechecked float levels-good. changed power valve although old one seemed OK. I gave up and drove it to work today. On lunch I started it and pulled plug wires one at a time with it running(note.. didn't use wire puller, did it by hand at the plugs without getting shocked; think wires must be ok because each are firing when a timing light is clameped onto it). No change on # 1 or # six when the wires were pulled, so I changed those plugs. Didn't look bad, good brown suit on them. Changed them anyway. Still runs same. I've checked for vaccuum leaks (brakeclean) and can't find any. Could be one on the underside of vallypan and wouldn't find it though. Doesn't have any blowby either. Not many parts to a holly and I 've never know a carb problem to create such a dead miss, but what is left????? I can't believe its the module or distributor becase its such a dead miss and a clamp on light shows their all firing. Wish I had access to an old sun machice, but I don't. Might try to rebuild an old frozen-up (blades) carb and try it next week on my days off. Might have to change my username to stumped in Illinois. LOL
